Ohaus Troemner OIML Precision Weights (USA) Weight Set F2 Wt Set(12), 500 mg-1 mg, NVLAP 30390852

The Ohaus Troemner OIML Precision Weights (Part Number 30390852) is a set of calibrated reference weights ranging from 1 mg to 500 mg designed for precise mass calibration and verification of analytical balances and weighing instruments.

Key Features:

• OIML Class F2 accuracy
• Weight range from 1 mg to 500 mg
• Set capacity: 1.11 g total
• Set contains 12 pieces: 1 mg, 2 mg (2 pcs), 5 mg, 10 mg, 20 mg (2 pcs), 50 mg, 100 mg, 200 mg (2 pcs), 500 mg
• Weights from 5 mg to 500 mg made of 316 stainless steel
• Weights below 5 mg made of 3003-H14 aluminum
• Density at 20°C: 7.95 g/cm³ for 500 mg to 5 mg weights; 2.70 g/cm³ for weights below 5 mg
• One-piece construction per weight
• Includes protective case sized approximately 4.5 in x 3.5 in (11.43 cm x 8.89 cm)
• Manufactured in USA

Advantages:

• OIML Class F2 ensures consistent high-level precision suitable for analytical calibration
• Wide weight range with multiple units allows fine incremental calibration across low mass values
• Use of corrosion-resistant 316 stainless steel improves durability and chemical resistance for weights 5 mg and above
• Aluminum weights below 5 mg reduce mass variability due to lower density material
• Compact protective case enables safe transport and organized storage of the entire set
• One-piece construction enhances dimensional stability and ensures integrity during handling
